HTC M8 Stuck on HTC Screen

Hello everyone.
I work as a device technician(phones, tablets, computers) to pay my way through college. So I bought this HTC M8 off of a friend of a friend. Initially it was a screen repair job and he couldn't pay me so I bought it. Once i fixed it the back camera didn't work, couldn't see a problem with the hardware but anyway. I bought the phone from him. After taking it apart a 3rd time when it was put back together it would not go past the HTC One Screen. It can be charged and does the splash screen from the carrier but gets stuck. Now I can get into the HBoot menu as seen here.

Sorry for the bad image(another phone i'm fixing to sell. Smashed camera in case you were wondering).

I have read a bit about this on a few forums. I've tried Factory Reset. And Power button and Volume UP.
I saw something that it could be. I may have deleted the OS and it can't go any further because there is nothing to go to. Any help is very much appreciated.
 
If you work as a device technician I guess you are familiar with fastboot? If not, look here.

With fastboot set up on your computer, put the phone in fastboot mode from the hboot menu, connect via usb and type the command "fastboot getvar all". Post the results here (edit out the serial number and IMEI) and that will help us identify what ROM Update Utility package you need to reflash the phone.

That said, since the bootloader is locked and the NAND security flag is set On you shouldn't be able to delete the OS. But if there is any software issue an RUU should clear it, but you need the right one for the phone or else it just won't run.

Hey thanks for the reply. When I go to put the phone in fast boot I'm prompted with this menu

I'm not sure which to pick if it matters at all.
I have this fast boot installed. http://forum.xda-developers.com/showthread.php?t=2317790
Will that still work?
 
Pick nothing, you need to be in FASTBOOT USB mode for the command to work (plug in to PC, it'll change from FASTBOOT to FASTBOOT USB).

You can use that fastboot if you already have it installed.

Hey that was a great help thanks. But it still says waiting for device. Mind i read the other one and it said usb debugging has to be enabled. I can't do that if it matters seeing as i can't get into the phone.
 
Usb debugging starts the adb daemon (service) on a running phone. Adb has no place at this point - only fastboot.

If you plug in and say in the command window -

fastboot getvar all

It says waiting for devices?
